Why Is a Firewall Important?
A firewall acts as the first line of defense for your network, protecting your devices and data from cyber threats. It is a critical component of any secure network for the following reasons:
Enables Remote Work Safely
Firewalls secure connections for remote workers by protecting Virtual Private Networks (VPNs), ensuring safe and encrypted access to your business’s internal network.
Blocks Unauthorized Access
Firewalls monitor incoming and outgoing traffic, ensuring that only trusted connections are allowed. This prevents unauthorized users or malicious software from accessing your network.
Protects Against Malware and Viruses
By filtering traffic, firewalls can block malicious files and programs before they reach your devices. This reduces the risk of infections from ransomware, spyware, and other forms of malware.
Enhances Privacy and Security
Firewalls help keep your sensitive information private by preventing hackers from intercepting data. This is especially important for businesses handling customer data or financial transactions.
Controls Network Traffic
Firewalls allow you to set rules for what kind of traffic is allowed, giving you control over the data that flows in and out of your network. This can prevent misuse of your network resources.
Customizable Security Policies
With advanced firewalls, you can implement security measures tailored to your needs, such as blocking specific websites, restricting certain types of content, or limiting access based on user roles.
Protects Against Network-Based Attacks
Modern firewalls can detect and prevent Distributed Denial-of-Service (DDoS) attacks, man-in-the-middle attacks, and other sophisticated threats that target your network’s vulnerabilities.
Regulatory Compliance
Many industries have strict regulations regarding data protection. Firewalls help ensure compliance by providing an essential layer of security to protect sensitive information.
What Is a Managed Network?
A managed network is a network infrastructure that is monitored, maintained, and optimized by IT professionals, often provided as a service by a third party or an internal team. It ensures that all devices, systems, and connections within the network operate efficiently, securely, and reliably.
Managed networks typically include:
Scalability and Optimization
Managed networks are designed to grow with your business and ensure the infrastructure is optimized for current and future needs.
24/7 Monitoring
Continuous oversight to detect and address issues like downtime, security breaches, or bottlenecks before they affect performance.
Maintenance and Updates
Regular updates to software, firmware, and hardware ensure the network remains secure and performs at its best.
Troubleshooting and Support
IT experts diagnose and resolve network issues, reducing downtime and minimizing business disruptions.
Security Management
Firewalls, intrusion detection systems, and regular security audits protect your network from cyber threats.
What Is a “Bottleneck” in Networking?
A bottleneck in networking is like a traffic jam on a road. Even if the rest of the highway is wide and clear, a narrow or congested section slows down the flow of cars. Similarly, in a network, a bottleneck occurs when one part of the system can’t handle as much “traffic” (data) as the other parts, causing delays.
What Is Cybersecurity?
Cybersecurity is the practice of protecting computers, servers, networks, and data from unauthorized access, attacks, or damage. It involves technologies, policies, and practices designed to defend against threats like hacking, malware, phishing, and ransomware.
Having antivirus software on your PC is a good start, but it isn’t enough. Cyber threats are becoming increasingly sophisticated, using tactics like zero-day exploits and ransomware that antivirus software alone often cannot handle.
Antivirus mainly detects and removes malicious files but doesn’t protect against phishing, social engineering, or network-based attacks like Distributed Denial of Service (DDoS).
Cybersecurity requires multiple layers of protection, such as firewalls to block unauthorized access, encryption to secure sensitive data, and multi-factor authentication for added account security.
Tools like intrusion detection systems can monitor and alert on suspicious activity to catch issues before they escalate.
Your network can also be a vulnerability. Connecting to an insecure network, like public Wi-Fi, can expose your device to attacks, even if antivirus software is installed.
To enhance cybersecurity, use a firewall, keep all software updated, and adopt strong, unique passwords. Multi-factor authentication provides an added layer of protection. Avoid clicking on suspicious links or downloading unknown files. Regularly back up your data to protect against ransomware or hardware failure. For businesses or critical systems, professional cybersecurity services are often necessary.
While antivirus software is an important component of security, it’s just one piece of a larger strategy to protect against modern cyber threats.
Using the firewall provided by your Internet Service Provider (ISP) might not be good enough for several reasons. ISP firewalls are often basic and don’t offer advanced protection features, which means they may miss some types of online threats.
These firewalls mostly protect the connection coming into your home, but they don’t secure the individual devices inside your house, like your computer or phone.
With an ISP firewall, you might not be able to change settings or control how it works, making it harder to fine-tune your protection to fit your needs.
ISP firewalls may not always be updated quickly enough to keep up with new types of attacks.
They don’t offer some extra protections like filtering out dangerous apps or checking deeper into your network traffic for hidden threats.
ISP firewalls are designed to protect many customers, so they might not be specific enough for your individual needs.
If there’s an issue with your ISP’s firewall, you might not know about it, leaving your network exposed.
For stronger security, it’s a good idea to have an extra firewall that you can control and customize to fit your needs, giving you better protection against threats.
What’s a UPS? What are they used for? How do they protect me?
A UPS, or Uninterruptible Power Supply, is a device that provides backup power to your devices in case of a power outage. It ensures that you don’t lose power unexpectedly, giving you time to save your work or safely shut down equipment. UPS units also protect against power surges, which can damage sensitive electronics.
They are commonly used for computers, servers, home entertainment systems, and networking equipment, but they can be helpful for any device that needs a constant and stable power source. The UPS works by storing energy in batteries, so if the main power source fails, it automatically switches to the backup power without you noticing.
In addition to providing backup power, a UPS protects against issues like voltage spikes and electrical surges that can occur during storms or when the power grid experiences problems. These surges can damage or destroy electronic equipment, but a UPS helps absorb and redirect the excess power, keeping your devices safe.
Back up storage – Why is it important?
Backup storage is important because it ensures that your important data is safe in case of unexpected events like computer crashes, hardware failures, or accidental deletion. Without a backup, you could lose files that are hard or even impossible to recover, such as photos, documents, or business data.
Having a backup means you can restore your data quickly if something goes wrong. Whether it’s a hard drive failure or a cyberattack like ransomware, backup storage gives you peace of mind, knowing your data is secure and recoverable.
Backup storage is also helpful in case of accidental deletion or mistakes. If you accidentally overwrite a file or make an error, you can recover the previous version from your backup. It’s a critical step in protecting your information from both technical issues and human errors.
2FA, or Two-Factor Authentication – what is it?
2FA, or Two-Factor Authentication, is an extra layer of security for your online accounts. It works by requiring two forms of identification to access your account. The first is usually something you know, like a password. The second is something you have, such as a phone or security key.
When you log in to an account with 2FA enabled, you’ll enter your password as usual. Then, the system will ask for a second form of verification, like a code sent to your phone via text or an app. This makes it much harder for hackers to get into your account, even if they have your password, because they would also need access to your second factor (like your phone).
2FA significantly improves security by adding that extra step to the login process, reducing the chances of unauthorized access.
What is an Access Point? Isn’t my internet provider setup good enough?
An Access Point (AP) is a device that allows your wireless devices, like smartphones, laptops, or smart TVs, to connect to your network. It acts as a bridge between your wired network (like your router or switch) and the wireless devices in your home or business. The AP takes the internet signal from your router and broadcasts it as a Wi-Fi signal, allowing you to connect to the internet wirelessly.
Your internet provider might give you a router that includes built-in Wi-Fi, but that might not be enough depending on your needs. The Wi-Fi coverage from a provider’s router can be limited, especially in larger spaces or areas with thick walls. This can lead to weak or slow connections in certain parts of your business or office. An Access Point can extend your network’s range, giving you better coverage in those areas.
In addition, dedicated Access Points usually provide more advanced features like better security, higher speeds, and more customization options compared to the basic Wi-Fi included with your internet service. If you need stronger or more reliable Wi-Fi, adding an Access Point is a good way to improve your wireless network.
Why having a guest network is good
Having a guest network is especially important for businesses because it helps maintain the security and performance of your main network. By providing a separate network for visitors, clients, or contractors, you can keep your internal systems and sensitive data protected. Guest users can access the internet without being able to see or interact with your company’s resources, reducing the risk of accidental or intentional breaches.
A guest network also allows businesses to manage bandwidth more effectively. With separate networks, you can ensure that guest usage doesn’t slow down the performance of critical systems or affect the work of your employees. This helps maintain a high level of productivity and ensures your business operations continue smoothly.
Additionally, having a dedicated guest network gives you better control over security settings, such as using different encryption methods or requiring a password that is changed regularly. This added layer of security helps minimize the potential risks associated with outside access, protecting your business from potential cyber threats.
Do I need my device(s) upgraded for faster connections?
Upgrading your device for faster connections depends on several factors, including the type of device, your network, and your business needs. If your current device (like a laptop, desktop, or smartphone) is older or doesn’t support the latest Wi-Fi standards, upgrading may help improve connection speeds. Devices that support newer Wi-Fi technologies, such as Wi-Fi 6, can provide faster, more reliable connections, especially in environments with many devices connected at once.
However, upgrading your device isn’t always necessary if your internet plan or network equipment is the limiting factor. For example, if your internet speed from your service provider is slow or your router isn’t capable of handling faster speeds, upgrading your device alone won’t make much of a difference. In that case, upgrading your router or switching to a higher-speed internet plan might have a bigger impact.
If your business requires quick access to large files or multiple users need to be connected at the same time, upgrading devices to support faster connections can enhance productivity. But for basic internet use, older devices might still perform adequately, depending on your network’s overall setup.
Why Upgrading Your Devices Enhances Security and Performance
When it comes to security, newer devices typically offer better protection than older ones. As technology advances, so do the security features and protections built into devices. For example, newer devices often come with up-to-date encryption standards, more secure authentication methods (like biometric login), and better protection against modern cyber threats such as malware and ransomware.
Older devices, on the other hand, may not support the latest security protocols. They might not receive software or security updates anymore, leaving them vulnerable to known threats. If a device is running outdated operating systems or firmware, it could become an easy target for hackers, putting your business’s data at risk. Additionally, older devices might not support the latest security features like WPA3 encryption for Wi-Fi, which offers stronger protection against unauthorized access.
If your business relies on devices that are older and no longer supported with security updates, it’s important to consider upgrading them. Newer devices come with advanced security built in, reducing the risk of potential breaches and keeping your company’s data safer. While older devices may still be functional for basic tasks, their lack of updated security features makes them a significant risk, especially if they’re connected to a network with sensitive company information.
Why do I need a server? What are they for?
A server is important for businesses because it helps manage, store, and share data, applications, and other resources within your network. Servers are used to centralize your company’s information, making it easier for employees to access files, collaborate on projects, and use business software securely and efficiently.
Servers handle various tasks such as hosting websites, managing emails, storing large amounts of data, and running applications that multiple people in your business need to access. They can be set up to manage security, backups, and user permissions, so you can control who has access to specific files or systems.
For example, instead of storing files on each individual employee’s computer, which could lead to confusion or loss of data, a server allows everyone to access the same central location. This makes data management simpler and more organized.
Additionally, servers often provide better security and reliability compared to using personal devices, ensuring that critical business information is kept safe, protected from cyber threats, and backed up in case of emergencies. Essentially, servers are key to keeping your business’s IT infrastructure organized, secure, and scalable as your company grows.
What’s a server rack and do I need one?
A server rack is a metal frame designed to hold multiple servers, networking equipment, and other hardware in an organized, space-efficient manner. It allows you to mount your devices vertically, saving space and keeping everything neat. Server racks are commonly used in businesses or data centers where large amounts of equipment need to be stored and accessed efficiently.
You might need a server rack if your business is using multiple servers or other equipment, like switches, routers, or storage devices, and you want to keep everything organized. A server rack makes it easier to manage the devices, as everything is in one place, neatly arranged, and easier to access for maintenance or upgrades. It also helps improve airflow and cooling for your equipment, preventing overheating and ensuring that your devices run smoothly.
If your business is growing and you have more networking equipment, or if you plan to scale your IT infrastructure in the future, a server rack can be a good investment. It not only saves space but also adds a layer of professionalism and makes it easier to maintain your equipment as your needs grow. If you’re only using a few devices or your infrastructure is still small, a server rack may not be necessary, but it can be a smart choice for businesses planning to expand their IT systems.
Why should I get cameras from Norwood Networking instead of off a online retailer?
Getting cameras from Norwood Networking instead of an online retailer also offers enhanced security for your business. Many consumer-grade cameras from online retailers have security vulnerabilities that can expose your system to potential hackers. These cameras are often not designed with robust security features, and some may even be accessible to the public if not properly configured, leaving your business at risk of unauthorized access.
Norwood Networking provides cameras that are designed with stronger security features to prevent unauthorized access. They are configured with the latest encryption standards and offer more secure storage options for your footage. By choosing Norwood Networking, you reduce the chances of your system being compromised, ensuring that your surveillance data remains private and safe from cyber threats. Their team also ensures your cameras are set up with the right configurations, so you don’t have to worry about vulnerabilities or improper settings that might expose your system to the public.
Just like this, this is one of many sites that look for open camera systems http://www.insecam.org/en/byrating/?page=1 they have over 12,000 open camera’s from business’s to peoples homes because they aren’t setup right or the installer/owner never changed the passwords from the default ones. I have seen people eat dinner in their own house, I do get in contact with authorities and Internet providers to inform the owners of this security risk so the issues can be fixed with a success rate of about 90%. But it’s an example of not setting up systems right the first time.
Secure Password manager
A secure password manager is a tool designed to help you store, manage, and protect your passwords and other sensitive information. It securely encrypts your passwords and keeps them in one central location, so you don’t have to remember every login or risk using weak or repeated passwords across different accounts. With a password manager, you can create strong, unique passwords for every account, which is key for protecting your business’s sensitive data.
Most secure password managers use strong encryption methods to protect your stored data, meaning even if someone gains access to the system, they won’t be able to read your passwords. Many also have additional security features like two-factor authentication (2FA), which adds an extra layer of protection when logging in. A password manager can automatically fill in login details for websites and apps, making it both convenient and secure to access your accounts.
By using a secure password manager, you significantly reduce the risk of password-related breaches, like having passwords stolen or guessed, while maintaining control over your online security. It’s a simple but effective way to ensure that your passwords remain safe and difficult for attackers to crack.
Many businesses still rely on simple passwords or write them down to make it easier for staff to access systems and accounts. While this may seem convenient, it creates significant security risks. Simple passwords, like “123456Aa!” or “passworD1!,” are easy for hackers to guess using common attack methods. Even worse, writing passwords down—whether on sticky notes, notebooks, or whiteboards—can lead to them being exposed to anyone who has physical access to the workspace.
This opens the door for unauthorized individuals to gain access to critical business information, potentially leading to data breaches or financial losses. If a password is written down and left unattended, it’s vulnerable to theft or misuse, especially in shared or high-traffic areas. Additionally, relying on weak passwords or the same password across multiple systems makes it easier for cybercriminals to breach multiple accounts with just one compromised login.
Using a secure password manager can eliminate these risks by storing and encrypting passwords in a centralized, protected location. This way, staff can access necessary credentials securely without needing to write them down or use easily guessable passwords. A password manager ensures passwords are strong, unique, and easily accessible, reducing the chance of breaches caused by poor password practices.
The Human Factor: Why People Are Often the Biggest Security Risk
People are often the biggest security risk to a business because they don’t always understand the dangers or recognize the tactics used by cybercriminals. Many employees, even with the best intentions, may fall victim to common attacks simply because they’re unaware of the risks. For example, hackers can easily impersonate someone important within the company—like a senior executive or a manager, new ‘co-worker’ or even by saying they are the IT tech and they have maintenance to do—and use that position to gain access to sensitive information. This is often done through social engineering tactics, where the attacker convinces an employee that they need to share confidential details or grant access to systems without realizing they’re being manipulated.
Additionally, employees may not always recognize the signs of a phishing attack or the importance of using strong, unique passwords for every account. Without proper training, they may unknowingly click on malicious links, open unsafe attachments, or reuse simple passwords across multiple platforms. These actions can provide attackers with an open door to sensitive company data, systems, or networks.
The best way to minimize these risks is by ensuring that employees are well-trained and constantly aware of the potential threats around them. When workers understand the importance of security protocols, recognize phishing attempts, and know how to identify social engineering schemes, they can help safeguard the business against attacks and keep company data secure.
What is PEN testing
Penetration testing, or pen testing, is a simulated cyber attack on your business’s IT systems conducted by ethical hackers or security professionals. The goal is to identify vulnerabilities—like weak spots in your network, software, or hardware—that could be exploited by malicious hackers. Pen testers use the same tools and techniques as cybercriminals but with permission, testing your defenses in a controlled and safe manner.
Pen testing isn’t just done remotely through computers. It can also include physical, in-person testing where ethical hackers attempt to gain physical access to your premises or devices. For example, they may try to bypass security measures like door locks or access cards, or attempt to steal company devices to see if they are left unsecured. They might also attempt social engineering tactics, such as posing as an employee or a vendor, to gain access to sensitive areas or information. These in-person tactics help reveal weaknesses in your overall security policies and physical infrastructure.
Once the test is complete, pen testers provide a detailed report that highlights the weaknesses they found, both digitally and physically, and offer recommendations to fix them. This helps businesses strengthen their defenses before real attackers can exploit these vulnerabilities. By regularly conducting pen tests, including both remote and in-person methods, businesses can stay ahead of potential security threats and ensure both their digital and physical security measures are up to standard.
It’s a lot easier than you think to get physical access, doors left unlocked, doors lacking security, alarm pin codes on sticky notes by the alarm panel, and talking to your staff to convince them we need access. Here is a great video on just how it easy it really is.
